Unfortunately, TikTok doesn't yet use superior security features like two-factor authentication. Thankfully, you can still make your TikTok account more secure by adding a verification code and changing a few key settings. Here's how.
How to Set Up a Verification Code on TikTok
Launch the TikTok app on your iPhone or Android device and then open the "Me" tab in the bottom right. Next, tap the three vertical dots to open the settings menu and then tap the "Manage My Account" option.
Add your phone number and email address here. Once you've added this info, TikTok will automatically send you a verification code any time you try to log in using your phone number.
You'll still be able to log in as usual with your username and password, but logging in with your phone number and verification code instead may be an easier alternative than remembering a complex and secure password.
How to Stop TikTok from Saving Login Info
TikTok will automatically save your username and password. If others ever use your phone, you can increase your security by telling TikTok to always launch without logging into your account.
To enable this setting, log in and tap the "Me" tab in the bottom right of the main screen. Select the three vertical dots in the top-right and then tap "Manage my Account". Deactivate the "Save Login Info" setting. Some Android, iPhone, or iPad devices may still try to save your password to that device.
How to See Who's Using Your TikTok Account
If you suspect someone of using your TikTok account, you can see which computers, smartphones, or tablets have accessed your account. From the app's Home screen, tap Me > three vertical dots > Manage My Account > Security. Any additional security alerts or warnings will be presented on this screen.
Select "Your Devices" to explore all the logged-in devices that your account has been used on.
TikTok is for sharing, so its security isn't quite as tight as apps that store more private information. While that may change in the future, these settings can help you keep a closer eye on anyone who may be trying to access your account. You may also want to protect your privacy by deleting your TikTok watch history and disabling profile views.
